Double Insulation
Class II materials, according to IEC 536, are designed with double insulation. This measure consists in doubling the functional insulation with an
additional layer of insulation so as to eliminate the risk of electric shock and thus not having to protect elsewhere. No conductive part of "double
insulated" material should be connected to a protective conductor.
Positive Opening Operation
A control switch, with one or more break-contact elements, has a positive opening operation when the switch actuator ensures full contact opening
of the break-contact. For the part of travel that separates the contacts, there must be a positive drive, with no resilient member (e.g. springs), between
the moving contacts and the point of the actuator to which the actuating force is applied.
Control switches with positive opening operation may be provided with either snap action or slow action contact elements. To use several contacts
on the same control switch with positive opening operation, they must be electrically separated from each other, if not, only one may be used.
Every control switch with positive opening operation must be indelibly marked on the outside with the symbol:
Snap Action
Snap action contacts are characterised by a
release position that is distinct from the operat-
ing position (differential travel). Snap breaking
of moving contacts is independent of the switch
actuator' s speed and contributes to regular elec-
tric performance even for slow switch actuator
speeds.
Slow Action
Slow action contacts are characterised by a
release position that is the same as the operat-
ing position. The switch actuator' s speed di-
rectly conditions the travel speed of contacts.
Contact shape according to IEC 60947-5-1.
Change-over contact elements with 4 terminals
must be indelibly marked Za or Zb.
See figure opposite for contact representation.
Utilization Category
AC-15: switching of electromagnetic loads of electromagnets using an alternating current (>72 VA).
DC-13: switching of electromagnets using a direct courant.
Minimum Actuation Force / Torque
The minimum amount of force/torque that is to be applied to the switch actuator to produce a change in contact position.
Minimum Force / Torque to achieve Positive Opening Operation
The minimum amount of force/torque that is to be applied to the switch actuator to ensure positive opening operation of the N.C. contact.
